The document presents a case study on a road safety audit conducted on the NH 8 stretch from Tarasali Flyover Bridge to Jambuva Bridge in Baroda, highlighting the importance of road safety and the significant rate of accidents globally and in India. It outlines the objectives and applications of road safety audits across various project stages, from feasibility to in-service assessments, aimed at minimizing risks and improving roadway safety. The findings from site visits and a checklist evaluation illustrate specific safety issues and recommendations for enhancements in the audited area.

3. Introduction
In most regions of the world,
 over 1.2 million people die every year due to road crashes.
 about 50 million suffer non-fatal injuries.
 In India,
 In 2010, No. of accidents around 5 lakhs and casualties 134,513 died
& 5 lakh injured.
 It means that 1 road accident every minute & 1 road accident death
every four minutes.
 53.1% of road accident victims were in the age group of 25 to 65
years.

4.  NHAI lunched massive Road Safety Audit Programs to carry out the audit
at different stages.
 On 11 May 2011, the Decade of Action for Road Safety 2011-2020 was
launched in more than 100 countries including India, with one goal: to
prevent five million road traffic deaths globally by 2020.

5. What is Road Safety Audit ?
 “A means of checking the design, implementation and operation of road
projects against a set of safety principles as a means of accident prevention
and treatment”.
 It is also the systematic checking of the safety aspects of new/existing
highway and traffic management schemes, including modifications to
existing layouts.
 Safety Audit can be applied on (a) new roads (b) existing roads.
 On new projects safety audit will lead to avoiding building road crash-
prone situations and on existing roads audit will lead to improved roads
from the safety point of view.

6. Objectives
 Minimize the risk of road accidents.
 Minimize the need for remedial work after construction.
 Reduce the whole-life costs of the project
 Improve the awareness of the safe design in the planning, design,
construction and maintenance of roads

7. Scope of study
 Future accident can be minimized.
 The loss of human lives can be reduced.
 The expenditure can be saved in remedial work.

8. Application of road safety audit
 Road safety audit may be carried out at any or all following stages
 Stage 1: Feasibility
 A safety audit can influence
 the scope of a project
 route choice
 selection of design standards
 impact on existing road network
 provisions of interchanges or intersections
 access control
 number of lanes
 route terminals, stage development, etc.

9.  Stage 2:- Draft design
 This audit stage is undertaken on completion of a draft plan or
a preliminary design. Typical considerations include
Horizontal and vertical alignment
Sightlines
Intersection layouts
Lane and shoulder width
Super elevation
Overtaking lanes
Provisions for parked and stationary vehicles
Provisions for bicyclists and pedestrians
Effects of departures from standards and guidelines
Safety during construction, etc.

10.  Stage 3:- Detailed design
 This stage is on completion of detailed design, normally before preparation of
contract documents, considerations include:
 Line markings
 Signing
 Delineation
 Lighting
 Intersection details
 Clearance to roadside objects
 Provision to road user groups with special requirements
 Temporary traffic management and control during construction
 Drainage
 Roadside objects
 Landscaping
 Batters
 Guard fencing, etc.

11.  Stage 4:- Pre- opening
 Prior to opening of the road to traffic
 The audit would involve driving, riding and walking through the
project to check the adequacy for the needs of all road users.
• Involve night-time inspection
• Inspection of both wet and dry conditions
 It would consider similar issues raised in stage 2 and 3, but with the
view of assessing their adequacy as actually constructed.
 Taking specific note of variations that might have occurred from the
plans in the process of construction.

12.  Stage 5:- In- service
 Systematic examination of sections of the existing road
network to assess the adequacy of the road, intersection,
roadside, etc. from an explicit safety viewpoint
This can have two applications:-
Monitoring a new scheme after it is opened to traffic.
i.e. in the weeks and months following the stage 4
audit
Safety audit of an existing road network with a view of
identifying safety-related deficiencies.

13.  Road safety audit can work in two ways:
 Removing preventable crash producing elements at the planning
or design stage
e.g. inappropriate intersection layouts
 Mitigating the effects of remaining or existing problems
Inclusion of suitable accident reducing features
• Anti-skid surfacing
• Guard fencing
• Traffic control devices
• Delineation, and etc.

14.  As part of our Project, our group members did preliminary Road
Safety Audit (RSA) of NH 8, in the stretch Tarasali fly over Bridge
to jambuva bridge (Km 5.4 ).

18. Checklists

19.  A set of checklists
 Use of checklists which show type of issues and problems that
can potentially arise at the relevant stage of the project.
 Checklists are a memory prompt.
 When using checklists, it is less likely to overlook problems.
 They can not be a substitute for expertise.
 One of the main benefits of checklists is that designers can use
that to audit themselves before their work gets to the auditor.
